The vast majority of electric vehicle owners charge their cars at home in the evening or overnight. They're doing it wrong, researchers say.

Electricity-generating rooftop solar cells can save a significant amount of water. In some states, individual household water saving can reach up to 1,000%.

"In principle, we can now scale semitransparent organic solar cells to two meters by two meters, which brings our windows much closer to reality."

How much energy is enough for each person to live a happy healthy life? New research finds it's a lot less than people use in many richer countries.

Offshore wind power could help lower wholesale electricity prices in six New England states, with low risk of turbine failure during extreme winter storms.

If just a third of the wind and solar projects proposed in Texas became reality, it could eliminate the state's remaining coal plants and their emissions.

A new method could be a big boost for solar energy. "This could really accelerate the production and deployment of perovskite solar panels and cells."

"Imagine an autonomous drone that powers itself with a solar array atop its wing that is 15 times thinner than a piece of paper. That's the promise..."

"Snow-phobic coatings, if we can demonstrate their long-term efficacy, will make solar power more reliable and more affordable in snowy regions..."

Researchers have boosted the efficiency of solar cells made from semiconducting perovskites while retaining their ability to stand up to the environment.
